Embodiment
Exemplary for describing the term of various embodiment.Should be appreciated that and provide these terms to be only help the understanding to describing, and using and defining of they never limits the scope of the invention.Term first, second etc. be used to carry out distinguishing between the object with same term and anywhere all and be not intended to represent time sequencing, unless otherwise indicated.Set is defined as the nonempty set comprising at least one element.
Fig. 1 illustrates the example context 100 that various embodiment of the present invention can be put into practice wherein.Environment 100 comprises two Radio Access Networks, such as, UTRAN and E-UTRAN network.Although use 3G network and 4G network carry out the method in interpreted environment 100, it all not limits the scope of the present invention to 3G and 4G anywhere.Therefore, the method can be explained by other network any.And environment 100 also can comprise the system element of more or less quantity to perform the method.
In one embodiment, environment 100 represents the typical architecture of single wireless voice calling continuity (SingleRadio Voice Call Continuity, SR-VCC) infrastructure.In environment 100, the subscriber equipment (UE) 102 in the first Radio Access Network 104 (also referred to as cell-of-origin) uses E-UTRANUu interface to be attached to E-UTRAN 106.E-UTRAN 106 is made up of multiple eNodeB entity (not shown).Multiple eNodeB entity uses S1-MME interface to be connected to mobile management entity (MME) 108.
In one embodiment, when the user of UE 102 initiates an audio call based on IP Multimedia System (IMS), then this audio call is anchored (anchor) in the application server (IMS) be associated with SR-VCC continuity.In one embodiment, the S1-U interface between E-UTRAN and service/PDN Gateway (GW) 110 is used for these data based on IMS audio call and signaling paths.In addition, between this service/PDN Gateway (GW) and IMS network entity 112, SGi interface is used.
In environment 100, when the user of UE 102 during an ongoing calling from a Radio Access Network (such as, cell-of-origin 104) when moving to another Radio Access Network (such as, Target cell 120), need to switch (HO).In one embodiment, when UE 102 moves to GERAN/UTRAN network 120 from E-UTRAN network 104 during ongoing audio call, then the HO from E-UTRAN network 104 to GERAN/UTRAN network 120 is needed.E-UTRAN only supports PS (packet switching) network and GERAN/UTRAN supports PS and CS (circuit switching) network.Therefore, UE 102 is from PS Network Mobility to support PS and CS network of network.
Therefore, the eNodeB in E-UTRAN 106 detects that needing to perform single wireless voice calling continuity to target GERAN/UTRAN network 120 switches (HO).Then, eNodeB sends switching by Sl-MME interface to MME 108 and requires message (handover required message).In one embodiment, MME 108 also receiving target cell ability.Such as, MME 108 receives the ability be associated with Target cell 120.Such as, the ability of Target cell comprises the ability of URAN/GERAN network.Such as, in this environment 100, Target cell is packet switching (PS) network and circuit switching (CS) network.
Then, MME 108 identifies that while HO process is carried out the voice bearer that is associated with UE 102 and non-voice carry.Subsequently, MME 108, by sending message via Sv interface to mobile switching centre (MSC) server 116, starts the switching of voice bearer to the CS territory of Target cell 120.Then, MSC server 116 is by sending the Session Hand-off that Session Hand-off (session transfer) request triggers IMS layer to IMS application server.
Then, MME 108 manages non-voice carrying.In one embodiment, when CS and PS network is supported in Target cell 120 and double-transmission mode (Dual Transfer Mode, DTM) switches, MME 108 starts to switch for the PS-PS of non-voice carrying.In another embodiment, when CS and PS network but when not supporting DTM is supported in the Target cell in the second Radio Access Network, non-voice carrying is hung up by MME 108.In yet another embodiment, when PS network is not supported in Target cell, MME 108 deexcitation non-voice carries.
In one embodiment, the PS-PS for non-voice carrying switches, and MME 108 sends message by S3 interface to SGSN 114.Prepare once Session Hand-off is initiated and completes to switch in Target cell 120, MME 108 just sends HO order via eNodeB to UE 102.When receiving this HO order, UE 102 moves to Target cell resource.Then, the existence of UE 102 is detected in Target cell 120.In one embodiment, UTRAN/GERAN 118 by this HO via Iu-cs/A interface notification to target MSC server 116 and via Iu-ps/Gb interface notification to target SGSN 114.In addition, to MME 108, MSC server 116 and SGSN 114 notify that switching completes via Sv and S3 interface respectively.Afterwards, MME 108 source of release community 104 is the resource that UE 102 retains.
Fig. 2 illustrates the first network element of the first Radio Access Network 200 according to one embodiment of present invention.In order to explain this first network element, reference will be carried out to Fig. 1.But those of ordinary skill in the art will be very clear, the present embodiment can be explained by any embodiment that other is applicable to of the present invention.
In one embodiment, this first network element is the node of other communication apparatus communication that the communication equipment making to be associated with forth generation communication network can and be associated with other communication network any.In one embodiment, first network element is eNodeB, and it is used to set up communication in E-UTRAN network.
In environment 100, first network element is associated with subscriber equipment (UE), and subscriber equipment is such as the UE 102 be associated with E-UTRAN network 104.First network element comprises transceiver 202 and processor 204.
Transceiver 202 in first network element receives the information be associated with one or more neighbor cell from UE.In one embodiment, transceiver 202 also receives the measurement report be associated with one or more neighbor cell from UE 102.In one embodiment, the measurement report Resource Availability that comprises signal strength signal intensity and/or be associated with one or more neighbor cell.
Processor 204 in first network element decides to perform the switching (HO) from the first Radio Access Network to the second Radio Access Network based on the measurement report of UE.Such as, processor 204 decides to perform the switching (HO) from the first Radio Access Network 104 to the second Radio Access Network 120 based on the measurement report of UE 102.Then, processor 204 identifies Target cell from one or more neighbor cell that measurement report provides.
In one embodiment, one or more neighbor cell is one or more communities that can be used for being performed by UE 102 handoff procedure.Therefore, one or more neighbor cell is one or more community that UE 102 is present in around UE 102 when shifting out the overlay area of the first Radio Access Network 104.In one embodiment, Target cell is the community of the execution HO process for UE selection.
In addition, Target cell ability determined by processor 204.In one embodiment, the identification of processor based target cell ability may perform the list of the carrying of HO to it and can not perform the list of the carrying of HO to it.In one embodiment, Target cell ability is the network support ability of Target cell.Such as, Target cell ability comprises the information about following content: Target cell is support circuit-switched (CS) network only, support both CS and packet switching (PS) UTRAN network, support that both CS and PS GERAN networks support that DTM and DTM switches simultaneously, support both CS and PS GERAN networks not support DTM but support that PS switches, or support both CS and PS GERAN networks but do not support DTM and do not support that PS switches.
Afterwards, transceiver 202 switching is required message (handover required message) and reorientate require in message (relocation required message) at least one send together with Target cell ability.In one embodiment, transceiver sends the list that may perform the carrying of HO to it.In one embodiment, switching requires that message is sent to core network elements together with Target cell ability.In another embodiment, reorientate and require that message is sent to core network together with Target cell ability.
